Nerve Agent
3 definitions

Nerve Agent

A potentially lethal chemical agent that interferes with the transmission of nerve impulses.

Nerve Agent

Organic esters of phosphoric acid used as a chemical warfare agent because of their extreme toxicity (tabun (GA), sarin (GB), soman (GD), GF, and VX).  All are potent inhibitors of the enzyme, acetylcholinesterase, which is responsible for the degradation of the neurotransmitter, acetylcholine.  Symptoms result from excess accumulation of acetylcholine in neuronal synapses or myoneural junctions.  Nerve agents are readily absorbed by inhalation and/or through intact skin.

Nerve Agent

A toxic substance that inhibits the cholinesterase enzyme and, therefore, elevates the acetylcholine level in the body.  Symptoms include pinpoint pupils, difficulty focusing, headache, and secretion from the skin and mucous membranes.  Nausea, vomiting, and loss of bladder and bowel control lead to severe dehydration.  These lead to general muscular fasciculation followed by violent convulsions, respiratory arrest, and death.
